A team of scientists has confirmed that essential star-formed elements like carbon follow a complex trajectory around galaxies, forming a vast circumgalactic medium. This medium acts as a dynamic "conveyer belt," ejecting and reacquiring these elements to fuel ongoing star and planetary formation. By using Hubble’s Cosmic Origins Spectrograph, the researchers detected significant carbon presence up to 400,000 light years away in intergalactic space. These findings suggest that this carbon recycling system supports continuous star formation, impacting galaxy evolution. Further research aims to uncover why some galaxies become inhospitable for new star formation.
